I am so sorry you & your friend are suffering so much! Its soul destroying watching someone you love hurt like that! It just isn't fair!
Words are empty right now, but know you are much loved, much valued, so very much appreciated! Despite everything you are going through you are still amazing, I know you can't feel that right now. (And thats okay) Just know that you are surrounded, loved and supported! I do hope you can feel a little of the warmth,love and care we all have for you! Consider yourself bear hugged!

You might find a role as a source of strength for your friend, I know how draining that can be. You can come here anytime to recharge, to vent, whatever. You have a whole community who cares about you.
